Flexible Solar Panel
Couleenergy flexible solar panel use unique shingled cell technology. Solar shingles are made by directly interconnecting the cells by placing them onto each other like roof tiles. In the process, solar cells are cut into smaller strips along the busbars. The main advantages of solar shingles are their aesthetic appearance, lower currents resulting in potential lower resistive losses, and a higher packing density for photovoltaic modules increasing the efficiency of flexible solar panels.
- The latest solar shingles technology.
- Bending over 30 degrees, without micro-cracks.
- Higher energy yield (≥15%) due to excellent shadow tolerance, low resistive losses, and temperature stability.
- Ultra-low weight, ＜ 2kg/m².
- Most elegant and aesthetic photovoltaic module, beautiful uniform design.
- 5-year warranty for workmanship and materials.
- OEM and ODM supported.
What is a ETFE solar panel?
ETFE (Ethylene-Tetra-Fluoro-Ethylene) is a high-strength fluorine polymer that is corrosion and stain resistant, non-stick self cleaning, and retains its clarity (and therefore light transmittance) ensuring long service life for photovoltaic modules, especially for bendable solar panels.
Advantages of shingled cells technology
1. Higher power output
Solar panel shingles technology, by cutting cells, with smaller current will help reduce “Cell To Module” loss, which means higher power output and more flexibility.
2. Lower internal resistance
The innovative shingled-cell technology allows no ribbon soldering internally and smaller branch current, which reduces internal resistance and improves the efficiency of the flexible solar panels. The unique parallel design reduces the hot-spot effect significantly, and the gorgeous aesthetic appearance will bring different visual enjoyment.
3. Bending over 30 degrees, no micro-cracks.
4. Effectively reduce power loss and hot spots resistance.
Under the test of shadow effect, the couleenergy flexible solar panels’ hot spot reached less than 50% heating of the conventional solar panels. It means if the flexible solar panel is in shadow or be covered by other things like birds droppings, it can effectively diminish the heat and avoid the photovoltaic module’s back sheet burning through.
Check below two different photovoltaic modules’ current running diagrams. You’ll find that even a little shadow wholly affects the left conventional solar panel.
5. More reliable than the conventional solar panels
With the solar shingles structure and no bus-bar design, the bonding adhesive can decompose the force of cells and diminish the fragment caused by any mechanical load.
Why flexible solar panel?
Solar-powered products are becoming more and more popular every day. This brings changes in technology associated with solar panels, going from the different materials of which they are composed of, to the different sizes, shapes, power outputs, and other features.
Unlike traditional solar panels that are thick and rigid, flexible solar panels can be bent up to a certain point. Flexible panels are lightweight, versatile, and more useful than framed panels. Allowing easy installation and transport, making them a plug and play product.
Also, flexible solar panels are capable of meeting a wide range of applications such as curved roofs, recreational vehicles (RV), boats/marine, and any curvy surfaces. Financially, flexible panels will likely reduce the installation cost of your solar array. Couleenergy flexible solar panels require less labor to install. They are much more portable and easy to handle than typical solar panels, which can be bulky and heavy and require heavy-duty roof mounting systems.
So, if you are thinking about installing flexible solar panels where a rigid solar panel won’t fit, do not hesitate to contact us.
